Understanding How Gastric Balloons Work

A gastric balloon is a medical device placed inside your stomach to help with weight loss. The procedure involves inserting a deflated balloon through your mouth and down your esophagus into your stomach. Once in place, the balloon is filled with saline solution (saltwater) or gas, depending on the type. This balloon takes up space in your stomach, making you feel fuller faster when you eat, which typically leads to eating smaller portions.

The balloon itself is made of soft, flexible silicone material designed to be gentle on your stomach lining. It floats freely in your stomach and does not attach to any tissue. The procedure to place the balloon usually takes about 15-20 minutes and is performed by a gastroenterologist—a doctor who specializes in the digestive system. Most people receive sedation during the placement to stay comfortable and relaxed.

There are several types of gastric balloons currently available. The Orbera balloon, one of the most well-known, stays in the stomach for six months. The Spatz3 balloon can remain in place for up to one year. The ReShape Duo uses two smaller balloons instead of one large balloon. Each type has different specifications regarding how long it can stay in your body and how much volume it provides. Your doctor will discuss which option might be most appropriate based on your individual circumstances.

The balloon works differently than weight loss surgery. Unlike gastric bypass or gastric sleeve surgery, which permanently changes your stomach's structure, a balloon is temporary and reversible. This means the device does not alter your digestive anatomy. When the treatment period ends, the balloon is deflated and removed through your mouth, and your stomach returns to its normal size and function.

Practical Takeaway: Understanding the basic mechanics of how a gastric balloon functions can help you have more informed conversations with your healthcare provider about whether this approach aligns with your weight loss goals and medical history.

The Placement and Removal Process Explained

Before your balloon placement appointment, you will need to undergo several preparation steps. Your doctor will order blood tests to ensure you are healthy enough for the procedure. You will also likely have an endoscopy beforehand, which allows your doctor to visually examine your stomach lining using a thin camera. This screening helps identify any existing stomach conditions like ulcers or inflammation that might affect your suitability for the balloon. For three days before the procedure, you will typically follow a clear liquid diet to ensure your stomach is empty.

On the day of placement, you will arrive at a medical facility, usually an outpatient endoscopy center or hospital. A nurse will place an IV line to deliver sedation. The sedation keeps you comfortable and relaxed but does not put you into deep sleep—you will likely not remember the procedure. Your doctor will pass a thin tube with a camera (endoscope) down your throat, allowing them to see inside your stomach. The deflated balloon comes through this tube and is positioned in the stomach. Once confirmed to be in the correct location, the balloon is carefully filled with saline or gas until it reaches the desired volume, typically around 400-700 milliliters depending on the balloon type.

After placement, you will spend a few hours in recovery while the sedation wears off. Some people experience nausea, stomach cramping, or discomfort in the first few days, which is normal. Your doctor will prescribe anti-nausea medication and may recommend a specific diet progression—starting with liquids, then moving to soft foods, and gradually returning to regular foods as your stomach adjusts. Most people return to normal activities within a few days, though strenuous exercise is usually restricted for the first week.

When it comes time to remove the balloon—typically at the six-month or one-year mark depending on the type—the removal procedure is similar to placement. You receive sedation, the doctor passes an endoscope down your throat, uses a special device to grasp the balloon, and deflates it before withdrawing it. The entire removal usually takes about 15 minutes. Recovery from removal is generally quick, with most people going home the same day.

Practical Takeaway: Knowing what to expect during placement and removal helps reduce anxiety about the procedures and allows you to plan time off work or arrange for transportation as needed.

Weight Loss Results and Timeline

Medical research shows that people using gastric balloons typically lose weight, though the amount varies from person to person. Studies indicate that patients lose an average of 10-15% of their body weight during the six-month balloon period. Some people lose more, and some lose less, depending on factors such as their starting weight, age, metabolism, diet adherence, and physical activity level. For example, someone weighing 250 pounds might reasonably expect to lose 25-37 pounds, though individual results differ significantly.

The weight loss pattern typically shows faster results in the first few months. Many people report losing 1-2 pounds per week initially, then the rate of loss may slow as time goes on. This is normal and expected. The balloon's primary role is to help you eat less by creating a feeling of fullness with smaller meals. The actual weight loss depends significantly on your food choices and eating habits. The balloon is a tool that works best when combined with healthier eating patterns and increased physical activity.

Data from clinical trials shows that people who combine balloon placement with behavioral support—such as working with a nutritionist or attending support groups—tend to achieve better weight loss results than those who use the balloon alone. This suggests that the device is most effective when you are actively working to change your eating habits and lifestyle. Your doctor or a dietitian can help you understand portions, balanced nutrition, and healthy food choices while the balloon is in place.

After the balloon is removed, maintaining weight loss becomes important. Some people regain weight if they return to their previous eating patterns. Others are able to maintain much of their weight loss because they have developed new eating habits during the balloon period. Research suggests that people who continue with the lifestyle changes and healthy eating patterns they adopted during the balloon treatment period are more successful at keeping weight off long-term. Some medical centers offer follow-up programs to support continued weight management after balloon removal.

Practical Takeaway: Realistic expectations about weight loss—understanding both typical outcomes and individual variation—can help you set achievable goals and maintain motivation throughout the balloon treatment period.

Benefits, Risks, and Side Effects to Consider

The primary benefit of a gastric balloon is that it offers a non-surgical option for weight loss. Unlike weight loss surgery, which requires anesthesia and involves cutting and rearranging your stomach or intestines, balloon placement is a minimally invasive procedure with no permanent changes to your body. The balloon can be removed at any time if problems develop, and your stomach returns to normal afterward. This reversibility appeals to many people who want to try a weight loss intervention without committing to permanent surgical changes.

Gastric balloons also require no special dietary restrictions after the adjustment period. You eat regular food, just in smaller quantities. This is different from some weight loss surgeries that require lifelong vitamin supplementation or restrict your ability to eat certain foods. The balloon works by creating early satiety—the feeling of fullness—rather than by reducing calorie absorption or permanently limiting stomach size.

However, gastric balloons do carry risks and potential side effects that you should understand. Common side effects in the first few weeks include nausea, vomiting, abdominal discomfort, and loss of appetite. These usually resolve within a week or two. Some people experience gastric ulcers, which are sores in the stomach lining. This occurs in roughly 2-5% of balloon patients. Symptoms include severe abdominal pain or black, tar-like stools. Balloon deflation or leakage can occur, though it is rare with modern balloons. If the balloon deflates, it may pass through your intestines naturally or need to be removed. In very rare cases, the balloon can cause intestinal obstruction, requiring emergency removal.

Certain medical conditions increase your risk of complications. People with a history of stomach surgery, severe acid reflux disease, inflammatory bowel disease, or bleeding disorders should discuss these with their doctor before pursuing a balloon. Pregnancy is also a contraindication—the balloon should not be placed during pregnancy. Some medications, particularly blood thinners and certain anti-inflammatory drugs, may need adjustment before or after balloon placement.

Practical Takeaway: Understanding both the benefits and potential risks allows you to have realistic conversations with your healthcare provider about whether a gastric balloon is appropriate for your health
